这是数据溢出导致echarts 圆环百分比呈现不规则图形。
起因举例来源于：data: [{...}]; value: 100 - value_huizong,
若当value_huizong大于100，则呈现溢出数据导致呈现负值，故问题产生。
解决办法：
判断思路：当每个模块数据大于100的时候，赋值100（但label中还是显示溢出数据，比方131%）,若小于100则显示正常值
最初成果与代码附上：
var myChart = echarts.init(document.getElementById('huizong'));
var data1 = { value: 131, //汇总 text: '汇总', color: '#FF543C', }; var data2 = { value: 79, //品质 text: '品质', color: '#3E88F0', }; var data3 = { value: 1221, //环保 text: '环保', color: '#2FD574', }; let value1 = data1.value || 0; let value2 = data2.value || 0; let value3 = data3.value || 0; if(value1 > 100){ value_huizong = 100; }else{ value_huizong = value1; }; if(value2 > 100){ value_zhiliang = 100; }else{ value_zhiliang = value2; }; if(value3 > 100){ value_huanbao = 100; }else{ value_huanbao = value3; }; option = { backgroundColor: '#fff', // tooltip: { // trigger: 'item', // }, series: [{ name: '汇总', type: 'pie', radius: ['35', '45'], center: ['15%', '35%'], hoverAnimation: false, label: { normal: { position: 'center' } }, data: [{ value: value1, name: data1.text, itemStyle: { normal: { color: data1.color, } }, label: { normal: { textStyle: { fontSize: 12, fontWeight: 100, color: data1.color, } } } }, { value: 100 - value_huizong, name: '占比', tooltip: { show: false }, itemStyle: { normal: { color: '#E0E3E9', } }, label: { normal: { formatter: value1 + '' + '%', textStyle: { fontSize: 16, color: data1.color } }, } } ] }, { name: '品质', type: 'pie', radius: ['35', '45'], center: ['48%', '35%'], hoverAnimation: false, label: { normal: { position: 'center' } }, data: [{ value: value2, name: data2.text, itemStyle: { normal: { color: data2.color, } }, label: { normal: { textStyle: { fontSize: 12, fontWeight: 100, color: data2.color, } } } }, { value: 100 - value_zhiliang, name: '占比', tooltip: { show: false }, itemStyle: { normal: { color: '#E0E3E9', } }, label: { normal: { formatter: value2 + '' + '%', textStyle: { fontSize: 16, color: data2.color } }, } } ] }, { name: '环保', type: 'pie', radius: ['35', '45'], center: ['81%', '35%'], hoverAnimation: false, label: { normal: { position: 'center' } }, data: [{ value: value3, name: data3.text, itemStyle: { normal: { color: data3.color, } }, label: { normal: { textStyle: { fontSize: 12, fontWeight: 100, color: data3.color, } } } }, { value: 100 - value_huanbao, name: '占比', tooltip: { show: false }, itemStyle: { normal: { color: '#E0E3E9', } }, label: { normal: { formatter: value3 + '' + '%', textStyle: { fontSize: 16, color: data3.color } }, } } ] }] } // 应用刚指定的配置项和数据显示图表。 myChart.setOption(option);
